Application filed June 13, 1916.

To all whom it may concern:

Be it known that I, ARTHUR DAVIS, a citizen of the United States, residing at Duguesne, in the county of Allegheny and tate' of Pennsylvania, have invented certain new and useful Improvements in Railroad-Ties and Rail-Fasteners, of which the following is a specification.

This invention relates to improvements in railway ties and rail holders or fasteners, and has for one of itsobjects to improve the construction and increase the efficiency and durability of devices of this character.

Another object of the invention is to provide a device of this character which couples the rail to the tie and firmly supports the rail, and in which provision is made for tightening the connection between the parts.

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claim; and in the drawings illustrative of the preferred embodiment of the invention- Figure 1 is a side elevation of a portion of a tie and end "elevations of the fastening devices, together with a railway rail, the rail being in transverse section;

Fig. 2 is a plan view of the parts shown in Fig. 1;

Fig. 3 is a transverse section of a tie and a side elevation of the fastening devices and the rail;

Fig. 4 is a detached perspective view of one of the combined brace and rail holding members;

Figs. 1, 2, 3 and 1- illustrate the device as applied to the rails intermediate the ends;

Fig. 5 is a side elevation of the fastening devices and portions of a pair of abutting rails, illustrating the manner of applying the improved device to a pair of rails at their confronting ends, the tie being in transverse section;

Fig. 6 is a side elevation of a'portion of the tie and end elevation of the braces and holding devices as arranged in Fig. 5, the rail being in transverse section on the line 6-6 of Fig. 5;

Fig. 7 is a plan view of the parts shown in Figs. 5 and 6.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

at 11 of the usual opening upwardly through the upper flange 7 and lower wider portions 13 extending through the vertical web. The portions 12 of the recesses are spaced apart a distance greater than the width of the flange of the rail, as shown, and are preferably slightly tapered or reduced toward one end. The material of the upper flange and the portion of the vertical web which is located between the recesses is increased in thickness, as shown in Figs. 1 and 3, the thickened portion extending the entire width of the tie.

The tie structure is thus materially strengthened and reinforced at the point where the greatest strains occur, or beneath the rail seat. Bearing against opposite sides of the rail are brace members 14:, each having a depending T-shaped projection, represented as a whole at 15, and corresponding to and fitting within the recesses 1213, the portions 15 being slightly tapered to correspond to the tapered form of the recesses. The upper brace portions 14 correspond to and bear against the web and flange portions of the rail and are each pro vided with a lateral projection 16 to receive holding bolt 17 which is tapped at its lower end into the adjacent face ofv the tie. The aperture for the bolt which is located within the projection 16 is elongated to permit the adjustment of the brace and its T- shaped projection 15. Each tie will be provided with a set of the recesses and the brace members, and the brace member 1 1, which is located upon the tie which receives the abutting end of a pair of rails, is provided with an integral clamp plate 18 of the usual form and apertured to receive the usual clamp bolts 19 which pass through the clamp plates and the webs of the abutting rails. The recesses in the ties may be formed in any suitable manner, either by cutting them therein with a suitable planer or other machine, the walls of the recesses being dressed relatively smooth, while the bearing faces of the projections of the the parts closely engage.

braces will likewise be tool dressed so that The recesses will be slightly smaller than the projecting portions 15 of the braces so that considerable force will be required to seat the braces upon the ties, thus preventing any tendency to work loose. The bolts 17 will be employed as a precautionary measure to prevent the parts working loose under the severe jars and strains to which they will be subjected.

As shown the member 14c15 corresponds in length to the total width of the upper flange of the tie, so that the full strength of the tie is utilized to support the brace members.

The improved device is simple in construction, and produces a tie and fastening of great strength and durability.

Having thus described the invention, what is claimed as new is:

In a device of the class described, a rail; way tie formed of a vertical intermediate Web and upper and lower lateral flanges and with transverse upwardly opening recesses spaced apart in the upper flange and in the adjacent portion of the web, the face of the upper flange between the recesses forming a rail seat, the recesses extending the full width of the tie and enlarged laterally at their lower ends and the material of the tie between the recesses increased in thickness to reinforce the rail seat, rail braces adapted to bear against opposite sides of the rail and each having a projection directed from the outer end and corresponding in shape to the recess and engaging in the same, and holding devices operating respectively through the braces and into the tie.

In testimony whereof I affix my signature.

ARTHUR DAVIS. [1 8.
